Abstract: An acoustic wave detector detects photoacoustic waves generated by absorbing measurement light emitted toward a subject, and reflected acoustic waves with respect to acoustic waves transmitted toward the subject. A preamplifier amplifies a detection signal output by the acoustic wave detector. A bypass unit is intended to output the detection signal without passing through the preamplifier. Controller causes the preamplifier to enter an operating state and selects a first path along which the detection signal is amplified by the preamplifier and then is input to the reception circuit as a signal path in a case where the photoacoustic waves are detected. The controller stops an amplification operation in the preamplifier and selects a second path along which the detection signal is input to the reception circuit via a bypass unit as the signal path in a case where reflected acoustic waves are detected.

Abstract: An X-ray imaging system includes an X-ray imaging apparatus and an access controller, which controls communication access of the X-ray imaging apparatus having an electronic cassette for forming an X-ray image and wirelessly transmitting the X-ray image. Before the electronic cassette starts transmitting the X-ray image, a priority request signal for priority of the first radio communication channel to the electronic cassette over a portable terminal device of radio communication is received. Upon receiving the priority request signal, presence of the portable terminal device is checked, in which a radio communication channel of overlap of frequency on the first radio communication channel is used. In presence of the portable terminal device with the overlap, the portable terminal device is regulated in communication regulation while the electronic cassette transmits the X-ray image. Also, the X-ray imaging apparatus is communicable by use of a communication network in wireless communication connection.

Abstract: An ultrasound system (1) includes an ultrasound probe (2), a mobile information terminal (3), and an external apparatus (4). The ultrasound probe (2) includes a transmission and reception circuit (22) that transmits an ultrasonic wave from a transducer array (21) and generates a sound ray signal, and a reception data generation unit that generates reception data before imaging based on the sound ray signal. The mobile information terminal (3) includes a camera unit (33) that acquires a view image. The external apparatus (4) includes a display controller (44) that displays an ultrasound image generated based on the reception data and the view image on an external monitor (45), and an input device (47). In a case where a probe freeze instruction is input from the input device (47), the transmission of the ultrasonic wave from the transducer array (21) is stopped.

Abstract: A breast imaging apparatus includes a radiation source that irradiates a breast of a subject with radiation, a radiation detector that detects the radiation transmitted through the breast to output a radiographic image, an ultraviolet light source that performs irradiation of ultraviolet light, and a controller that controls an operation of the ultraviolet light source. The controller prohibits the irradiation of the ultraviolet light by the ultraviolet light source in a case where a predetermined set condition is satisfied. The controller determines that the set condition is satisfied, for example, in a case where a person is shown in a captured image of a camera.
